It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] The protective film 4 includes an anti-corrosion layer 1 401, a buffer layer 402 and an anti-corrosion layer 2 403. One side of the anti-corrosion layer 1 401 is compounded with the buffer layer 402, one side of the buffer layer 402 is compounded with the anti-corrosion layer 2 403, and one side of the anti-corrosion layer 2 403 is compounded with an isolation layer 404. The thickness of the anti-corrosion layer 1 401 is the same as that of the isolation layer 404, and a reinforcement strip 6 is bonded to one side of the anti-corrosion layer 1 401.

[0026] Bolts can be used to connect the U-shaped frame 3 to the substrate 5. The U-shaped frame 3 can be used to reinforce one end of the protective film 4 to reduce the loosening of the protective film 4. The U-shaped frame 3 can support the bottom of the guide bar 2, which is convenient for the installation and use of the guide bar 2 on the top of the U-shaped frame 3. The two guide bars 2 can guide the installation of the horizontal bar 1, thereby facilitating the insertion of the horizontal bar 1 inside the guide bar 2. The horizontal bar 1 can assist in the installation and fixation of the top of the plate.

[0027] At the same time, the anti-corrosion layer 1 401 can wrap and protect one side of the substrate 5, the buffer layer 402 can improve the sound insulation and buffering effects of the protective film 4, the anti-corrosion layer 2 403 can improve the corrosion resistance of the protective film 4, and reduce the damage to the protective film 4 caused by corrosion, and the isolation layer 404 can improve the waterproof performance of the protective film 4, increase the functionality of the protective film 4, and reduce the damage to the plate during use.

[0028] Example 2: Figure 1 - Figure 3 As shown, one side of the reinforcement strip 6 is overlapped with the base material 5, and a plug-in rod is fixedly connected to one side of the reinforcement strip 6, a dividing rod 8 is inserted at one end of the plug-in rod, one end of the dividing rod 8 is fixedly connected to the inner wall of the base material 5, and an oblique rod 1 7 and an oblique rod 2 10 are inserted through the inside of the dividing rod 8, one side of the oblique rod 1 7 and the oblique rod 2 10 is overlapped with the reinforcement strip 6, and one end of the oblique rod 1 7 is fixedly connected to the side wall of the dividing rod 8, and the other end of the oblique rod 1 7 and the oblique rod 2 10 is fixedly connected to the inner wall of the base material 5, a filling cavity 9 is formed between the base material 5 and the oblique rod 1 7, the dividing rod 8, and the oblique rod 2 10, and the filling cavity 9 is filled with a filling block.

[0029] By overlapping the reinforcement strip 6 and the base material 5, the upper and lower sides of the base material 5 can be supported, thereby improving the overall strength of the board. The connection between the reinforcement strip 6 and the dividing rod 8 can be guided by the plug-in rod, which is convenient for the stable connection of the reinforcement strip 6 and the dividing rod 8. The two sides of the dividing rod 8 can be reinforced by the diagonal rod 1 7 and the diagonal rod 2 10. The inner wall of the base material 5 can be reinforced diagonally by using one end of the diagonal rod 1 7 and the diagonal rod 2 10, thereby improving the internal connection strength of the base material 5 and reducing the deformation of the base material 5 caused by external forces during use. A filling block is installed inside the filling cavity 9 to avoid the protective film 4 from being suspended during bonding, increase the contact area of ​​the protective film 4 with the reinforcement strip 6 and the base material 5, and improve the stability of the protective film 4 during installation.

[0030] The method of use and working principle of this device are as follows: first, put the filling block into the filling cavity 9, then adhere the protective film 4 to the side of the reinforcement bar 6 away from the substrate 5, so that the protective film 4 is tightly connected with the reinforcement bar 6 and the filling block, and then install the U-shaped frame 3 on both sides of the substrate 5 by bolts, and then insert the horizontal bar 1 between the two guide bars 2, and install bolts in the positioning holes 11 to fix the installation position of the horizontal bar 1. At this time, the remaining positioning holes 11 can be used to assist in the installation and fixation of the top of the PVDF film-coated board. When the membrane plate is in use, the diagonal rod 1 7, the dividing rod 8 and the diagonal rod 2 10 form a "M"-shaped structure. The "M"-shaped structure is symmetrically arranged up and down, and can support the inner wall of the substrate 5. The reinforcement strip 6 is connected to the dividing rod 8 through a plug-in rod, which can reinforce one side of the dividing rod 8 and improve the strength of the substrate 5. The anti-corrosion layer 1 401 is made of PVDF, the buffer layer 402 is made of foam material, the anti-corrosion layer 2 403 is made of vinyl ester resin, and the anti-corrosion layer 1 401 is made of polymer waterproofing agent coating.
